Understanding thermal transport in polymer semiconductors via two-channel mechanism.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The vibrational thermal conductivity of polymer semiconductors is critical to the performance of organic electronic devices, yet its underlying mechanisms remain elusive. This work presents a two-channel model to elucidate the vibrational heat transport in semiconducting polymers with extended side chains. We reveal a striking splitting of vibrational modes along the polymer chain, driven by the substantial difference in force constants between the backbone and side chains. This gives rise to two distinct dispersive longitudinal branches: a backbone branch, characterized by phonon-like propagons that govern thermal conductivity, and a side chain branch, consisting of non-propagating diffusons that make minimal contributions to heat transport. The reduced maximum thermal conductivity of these polymer semiconductors, compared to their side chain-free counterparts, is attributed to phonon scattering by the low-frequency optical modes of the side chains. Our findings establish a foundation for strategically modifying side chains as a potent approach to fine-tuning thermal conductivity.
